Testing remains an important part of reducing the spread of COVID-19. All New Yorkers should get tested for COVID-19 if they have symptoms or were recently exposed to someone with COVID-19. If you test positive after taking an at-home test, call your provider or 212-COVID19 (212-268-4319) to discuss treatment options.
See below for more information about when to get tested, the types of COVID-19 tests available and how to interpret tests results, including what to do if you test positive.
Everyone should get tested:
People who are vaccinated should still get tested. The COVID-19 vaccines cannot cause you to test positive.
If you recently recovered from COVID-19, you generally should not get retested for COVID-19 for three months after your symptoms began of, if you had no symptoms, from the date you were tested, unless you develop new symptoms.
With molecular tests, such as PCR tests, you may continue to test positive for COVID-19, even though you are no longer contagious. If you develop new symptoms, talk to your health care provider.
There are many health care providers, pharmacies and government facilities, including mobile and pop-up testing sites, offering testing — often free — throughout the city.
Here are some resources to help you find a location near you:
When you go for a test, you will not be asked about immigration status.
Most at-home tests allow you to test the sample yourself and get results in minutes. Some tests have you collect a nasal or saliva sample and send it to a laboratory.
Be sure to carefully read and closely follow the manufacturer’s instructions. You can also watch the below online instructional videos provided by the manufacturers before taking the test.
At-home testing may be less accurate than tests performed by a health care provider. In some cases, you should go to a provider for a test to confirm your initial results.
Note: At-home test results may not be accepted for some purposes, such as school, employer or travel testing requirements.
There are several different types of tests. Your health care provider can help you decide which type of test is best for you based on the reason for testing, such as recent exposure, presence of symptoms or periodic testing.
Molecular tests, such as PCR tests, can detect the virus even if there is only a small amount in your system. Some people test positive with a PCR test weeks or months after having COVID-19, even though they are no longer contagious.
These tests look for genetic material from the virus that causes COVID-19 (SARS-CoV-2). They usually require the specimen to be sent to a laboratory, which is why it may take a few days to receive results. A unique process used at COVID-19 Express sites allow for molecular tests to return results usually within a few hours.
Antigen tests (often called rapid tests) look for proteins on the surface of the SARS-CoV-2 virus.
Antigen tests usually can be processed at the testing site, or at home when using an at-home test, and results are ready quickly. Antigen tests may not detect the virus if you were infected recently or have small amounts of virus in your system. For this reason, there are times when you may need a follow-up molecular test, such as when you have COVID-19 symptoms but tested negative.
Antibody tests check the blood for COVID-19 antibodies — special proteins that the body produces to help fight off infection. They require getting a blood sample through a finger stick or drawing blood from a vein in your arm.
A positive test result means that COVID-19 antibodies were detected in your blood. The antibodies could be from having had COVID-19 in the past, from vaccination or from both.
Antibody tests cannot test for immunity to COVID-19. They should not be used to decide whether to get vaccinated, as vaccination is recommended even if you have had COVID-19.
If you test positive for COVID-19, immediately separate yourself from others and contact your health care provider, who can talk to you about how best to manage the infection.
If you do not have a provider, call 212-COVID19 (212-268-4319).
